The Pentax angled PF-EDAII spotting scope features a 45-degree slanted lens barrel for comfortable viewing in just about any situation. This scope is designed for high-precision outdoor viewing, along with enhanced optical quality which provides truer color tones. With porro-prism optics and a 65mm objective lens with extra-low dispersion optical elements, it delivers sharp, high-contrast images. Viewing in inclement weather won't be a problem as the PF-65EDAII is waterproof and nitrogen filled (JIS Class 6).
